It consists of a composite thickness of more than 6,500 feet (>2,000 m) of flat-lying basalt lava flows and covers an area of nearly 200,000 square miles (500,000 square km) (roughly the size of the states of Washington and Oregon combined) in west-central India.
State shift in Deccan volcanism at the Cretaceous-Paleogene
2015年10月2日 · Massive eruptions formed the Deccan Traps flood basalts in India at around the same time as the mass extinction event 65 million years ago. Renne et al. precisely dated the massive volcanic field, which suggests a simultaneous increase in volcanism associated with the famous Chicxulub impact.
Deccan Traps: Volcanic Climate Change & Dinosaur Die-Offs
The Deccan Traps date back to around 66 million years ago, when magma from deep inside Earth erupted to the surface. In some parts of the Deccan Traps, the volcanic layers are more than two kilometers (1.2 miles) thick, making this the second-largest volcanic eruption ever on land.
